Lifts — or elevators if you're from foreign parts — have received much love on these pages, but we shouldn't forget the lift's less glamorous and sibling: the escalator.
Most of us take escalator rides on a daily basis. The tube obviously stands head and shoulders over the rest, but there are escalators in office buildings too, not to mention quirky examples like that of the Natural History Museum.
Escalators offer photographers the chance to capture light entering a dark space, the flow of people and the symmetry of a mechanical process. Arguably the best spot in the capital is Canary Wharf, where a rank of escalators rise towards a glass ceiling, as demonstrated by the atmospheric opening image to this selection.
